I'm currently watching the series. I'm upto episode 9. The series is very bloody and sexually explicit, especially in the first episode. This almost made me stop watching, because it felt like it had no substance. The show gets more engaging when they introduce Kouta, Yuka and Mayu; they show each of these characters and their different psychological problems and this makes it very moving. There still is fanservice, like Nyuu running around naked or her fondling people inappropriately, but at least it now seems it is a secondary element. Ikki Tousen is pretty much pure fanservice and although it has good animation and character designs, as well as good action sequences with good music, it is ecchi. I think my favorite character so far is the Diclonius Nana (7).

first i watched for the echi factor and then i left for other anime because i am really not able to buy any products for it so i cant do anything because i am doing this all behind my parents back. i whent to lucky star, then robotech on manga then ikki tousen which lead me to a websight called danborou which i looked up elfen lied just for old times then i actually thought about the cool story. so i am now back on it
